A difficult situation for your Catholic friend. If she is divorced to the Jewish once divorced man and she wants to marry a Roman Catholic she will need an annulment of the marriage with the Jewish man. An annulment of a marriage the RC church never recognized in the first place.
The sad thing is how she went priest-shopping, trying to find one who would tell her she was in good standing with the church without changing anything. I tried to tell her that even if she found a priest who would tell her that, he’d be lying to her. The Catholic church’s rules are what they are. She either needed to stop sleeping with her husband, get him to convert to Catholicism, or whatever would make it right...or find another religion that didn’t think she was an adulteress. I still remember the agony she went through. I’ve lost touch with her except for exchanging Christmas cards, but I imagine this issue probably contributed to her divorce.
